Why have people been unable to harness nuclear fusion for the generation of electricity? a. We have not been able to determine a way to convert the energy generated into electricity. b. So far, the amount of energy necessary to initiate and sustain fusion on Earth is greater than the amount of energy produced in the fusion process. c. We cannot generate the magnetic fields necessary to initiate fusion events. d. It is too expensive to generate the atoms capable of undergoing fusion.
